I am trying to get some information from swf file using hexagonit.swfheader module.The orig file width and height are 160x600 and the size is 32.63 kB.

When I tried to get the same information by using hexagonit.swfheader everything matches except size. It displays size as 55890. I am not very good at math but is there a way to convert size 55890 to match 32.63 kB ?

Yes, just divide by 1024.But it won't match the actual file size; your file is compressed, and this is the size of its uncompressed contents.I don't think the file's actual size is stored in the header.

If you want to get the actual size of the file on your system, you can simply use os.path.getsize()
